Has the truck ever been hit? Sounds like something is out of whack in the back end...
Worn shocks wouldn't cause one edge of the tire to wear more than the other... Shocks could make the tires wear very odd across the tread, but it is not typically uniform all the way around the tire.
Another thing... Have these tires always been on the back?

thats what my step dad said about the shocks . yes these tires have only been on the back as well as the other 3 set tha had been on it. it has been hit but it was just a a small deal and it was just behind the drivers door. i dont really think it would have knocked anything out of wack. it happened before i bought it but i bought it from a friend and i know how it was hit. do you think i caould have a warped half shaft on the driver's side? it takes it about 8000 or maybe a little more miles for irt to really start showing.

well go to townfiar tire habve it laser aligned, i think its free, it is where i work anyways, but when we get wear patters like that its usually becasue of over or under infaltion, wrong rim(too small), it could jsut be the actual tire< im assuming thos are low profile? most low profile tires we do the tread is almost gone afther a 100K, i personally dont know why, and i dont think thats the case in urs since its only one,, but i think you know the correct psi and all thenonsense, so have it looked at by a couple people, double cheak the rim size and if the tire is seated properly on the bead

HEY TIPPMAN- this not the only set that has done it. i have 3 different sets of wheels on my blazer, they all have done. and the current tire calls for a 8.5 eide rim and thats what mine are, its not air pressure, have plyed with that and irt dont change. its something more in depth than bad tires or wheels i woud agree w/ you if it only done it to this set of tires but it has done it to all of them.

Is it possible to post a pic?
Is it cupping or feather edged, if you run your hand along it is it kinda smooth in one direction and grab your hand in the other direction?
Do you get any vibration at any speed while driving?
How do ya like that, you ask a question and I ask you three?!!!

lol yea i was looking for answers not questions. just kidding, its feathering the inside edge. i get a bad vibration at speeds about 80+ but other than that not really any vibrations. it doesn't grab my hand either way i run my tire over my hand it just hurts. lol j/k it feels smooth in both directions. i have these pix but they are with a cell phone i dont have my camera today my parents took it to the titans game this weekend. sorry hopefully these will help if not i will some more this week when i have my camera
the 1st pic is the outside of the tire and 2nd is the inside you can tell the difference. and its only wearing that inside part the rest is fine

If you don't rotate your tires, the left rear will wear faster than the others. As for the wear on the insides - check the axle tubes, they may be bent. eg minor accident, sliding in to a curb. You are lowered so you may have hit your bump stops a little hard from time to time.

i dont hit the bump stops ever. it was not slid into a curb either, the whole tire is not wearing fast as you can see in the pix
just curious how you come up w/ the left rear tire will wear faster? i just haven't ever heard that before

I have to agree... There is nothing that I can think of that would determine that the left rear tire would wear faster than any other tire unless you are either always spinning the tires or always making right turns...
Yeah, that is pretty bad. So it was hit on the driver's side... I'm wondering if the rear axle is still square with the frame. A 4-wheel alignment would tell you if it were out of line, but you should be able to check for a large discrepancy with a tape measure. Pick an identifying point on the frame that is the same on both sides. Measure forward from the inner lip of the rim to this point. If you see a difference, something has shifted in the back. I'm betting the measurement will be longer on the driver's side.

Sorry 30yrs + still working on the left, right thing.
When accelerating the torque of doing so places a little more force on the drivers side of the truck taking some away from the passenger side. There fore the passenger rear tire is more prone to slipping. Not saying you burn your tires off. Just the physics of motion.

That assumes that you are accelerating fast enough to break a tire loose... Under normal conditions and normal acceleration away from a stop light/sign, this shouldn't really ever come into play.

Then why do tires wear at all !!
But for fear of hijaking a thread , I wish not to discuss this further.
We have an alignment problem that needs adressing. So any one that has an idea of what to look for. Please enlight

Well, I suggested how to check the rear end in my previous post.
Tires wear through normal driving as well as from spinning. Side loading is the most promenant form of wear on a tire. Vehicles that are driven less aggressively wear the tires much less than those driven aggressively... Through your assumption that the passenger side tire wears more on solid rear axle vehicles due to acceleration... Just doesn't make a lot of sense. I get the whole weight transfer, frame torque, etc, etc, but it still just doesn't mean that tire always wears faster.
But I digress...

i have also wondered about the axle not being square. my step dad said it couldn't be aligned from the back. but im not real good w/ the alignmest stuff. are you talking something different than he is? he was telling me to get a 4 wheel alignment but then he looked under the truck and said differently. yes it was hit on the driver's side

There are no alignment modifications that can be done on the back as everything is rigidly mounted, but that does not mean that something isn't bent, causing your misalignment. That is what can be checked with a tape measure.
While you're under there, measuring, take a good look at where the spring mounts to the frame up front as well as where the spring mounts to the axle. Things should not be able to shift at the axle, but it is possible that during the accident the bolt holding the spring together sheared off, allowing the spring to slide on the top of the axle. What I would look for on top of the axle is signs that the spring has shifted.

ok i got you now i was misunderstanding you at first. i will have to try to measure it tommorow. im pretty sure the bolt has not sheared off because i have looked around under there but i will double check it
